1. Iron your fabrics well with a steam iron to avoid any shrinkage later on
2. Allow the fabrics to dry completely
3. Place the interfacing with the coated side down on the wrong side of the fabric
4. Cover with a damp cloth and press with the iron carefully for about 6 seconds step by step over each area - on the wool setting
5. Allow all the pieces of the fabric to cool flat for about 30 minutes so the adhesive can set properly
